To all whom it may concern.

lie it known that I, 01.01? N. TEVANDER,

The object of my invention is to provide an improved metallic lacing for driving belts and thecparticular object of the invention is to prom e an improved metallic lacing which shall be composed of pivotally joined or united members or parts, to the end that the lacing shall be freed from the strains which detrimentally afiect single metallic lacings. objects ter. vention consists in a metallic belt coupling, of the construction and "on of parts hereinafter and a. icularly pointed out in the claims.

In; inventions/ill be more readily understood by reference to the accompanying drawings forming a part of this specification,

which;

Figural re )resents two belt ends joined by a metallic acing or coupling embodying my invention; Fi 2 is a sectional view thereof on the line X X of Fig. 1; Fig. 3 is a similar view illustrating the pivotal action of the two members which compose thelacing or coupling; Fig. 4 illustrates the initial condition or commercial form of my improved coupling; andalso the method of applyi g the same to the belt ends; Fig. 5 is a section lil viewillustrating a coupling of greater size than that shown in the preceding figures; disclosing ivot bar portions of a modified form, which? I find advantageous in couplings the Larger sizes; and Fig. 6 is a perspective vi w: showing the two members of the coupl' hey'gppear before they are interthe prongs of one member are the other member.

My improved coupling preferably made m invention will a ear PP described e pu pose of this drawing being to i d or offset with relation to those of;

hngs being stamped from such materialand then formed into the bent or 4.5 sha e in which formthey are most readily applicable to the ends of belts. Each member of m coupling comprises in itself, a complete article of commerce or manufacture; and, the complete coupling-is, so to speak, made from such single piecepr member; that is to say, a single member oi suitable length is separated into two parts, and these parts, being interfrom sheet metal, the members of the couplociged, form the complete pivotal or hinge coupling. Thus lprefer to make my coupling members in long strips or lengths, which are afterward cutinto' shorter lengths to form couplings of commercial sizes. These long to t e end that they may take therefrom sections of s ecial lengths to fit belts of odd widths. it is my practice to make 1 these couplings rust proof, by tinning or otherwise plating the members of the son ling as they have been stamped and ormed.

soon as In the several figures of the drawings, only the terminal portions or connected'ends of a belt are shown and these are indicated by the reference characters A and 1B. I

As shown in the drawings member comprises a pivot bar gether with two jaws, the latter comprising two sets of prongs, 3 and 4, projecting from opposite ed es 0 the bar portion and having pointed en 8, 5, which are turned inwardly, to be driven into or through the belt. The length. of the sharp ends, 5, is greater than. the width of the p1votbcr portion, 2, of'the cou ler, and greater also than the thickness of t e belt, to the end that they may be clenched in the belt. The pivot bar portion, 2, is substantially straightf'a'nd as it corresponds to the end of the-belt, its width substantially equals the thickness of the belt, It may be considerabl T narrower, but should not be of 'reater widt 1 or thickness than the belt to W ich' the coupling is to be applied. Such are the requirements of my best shop practice, althou h it will be understood that misproportione couplings are sometimes a plied to belts, as when couplings me'nsions are not at hand. it will be noted that the prongs are widely separated, the

space between each two prongs bein suflicient to admit a prong of the'co-acting member. I prefer that the two rows or sets of rongs on each member of the coupling she be relastri s maybe furnished to users in strip form,

of proper i- P e slightly affected by 0 coupling serves as memberof the coupling. In other words.

lively L ends shall not interfere when driven into the belt, and also for the purpose of distributing the points of engagementvvith the belt.

the prongs and such parts of the barportions as are intermediate, in effect, serve only as rang-connectin parts, and are theretore but the strain ofthe belt. or suite of comparison it may be stated that in making my coupling members l. may place the integrally joined prongs directly' 0 posite each other on the pivot bur portion 0? the member. Members of this form may 40 be more easily placed together than those members which have relatively staggered prongs, but in such case the entire strain of the belt must be sustsiined by the intermediate parts of the pivot, leer portions, and

under excessive strains such .xortions would be apt to be bent, and there 3-, their etleef; iveness, lessened. Nevertheless, l. intend that the structure lest. defined. shall be in eluded within the scope 01 my invention, and

so in this connection desire to state, that. l do not confine my invention to specific constructions, exec. L as defined by the no pended claims, .or the r'eeson tliitt various modifictttions in the form and arrangement of the prongs and interconnecting bars or parts will readily suggest themselves to any one skilled in the art.

Aswvill now be clearly understood, the

cross bar portion, 2, of each member of my the plvot for the other the members are reciprocally, or self, inter locked, and the inner sides of the bar por- "tions engage in sdch manner that each serves stdeered, to the end that their sharp sveeov well shown in the drawings. In the smaller sizes of m v device the pivot bur portions. though llut. are so narrow that thev readily. rock upon one another without materially series ol integrellv 'oined staples, the two members being lin 'ed or interlocked to hinge. each upon the other. and the ends of the staples being turned and driven into. or

latter.

Having thus described my invention. 1 claim as new and desire to secure b v Letters Patent 1.
